Multikey Index GISt

["Leticia" <lgomez(at)itba(dot)edu(dot)ar>]

I need to implement a new GisT index that use multikey (i.e. tree columns).

I need to storage in the entry index the three transformed columns alltogether.

 

If a use “create index anIndex on tablename using ( atr1   atr1_ops,  atr2  atr2_ops,  atr3   atr3_ops) “,

I will obtain three separated invocation of “compress” function (one for each XXX_ops). I need to receive them in only one invocation. How can I do it using GIsT?

 

I am using PostgreSQL8.2.3. How does it work the multikey GIsT announced in the latest version of PosgreSQL?

 

Thanks a lot,

Leticia
